It would take 2.61 hours to fly from Dallas to Boston at 775 mph.

Since the time it takes to fly from Dallas to Boston varies inversely with the speed of the plane, to determine, if the trip takes 4.75 hours at 427 mi / h, how long would it take at 775 mi / h, the following calculation must be performed:

  • (427 x 4.75) / 775 = X
  • 2028.25 / 775 = X
  • 2.61 = X

Therefore, it would take 2.61 hours to fly from Dallas to Boston at 775 mph.
